This is a little obscure so I'm having trouble searching for it. We're a charity and are having an event where people can donate money at the door, at different levels (e.g. $100 as a 'guardian', $200 as a 'supporter', etc.) We'd like to display a scrolling list of these names on a tv screen in the room, and be able to add more names as the evening progresses. Can anyone provide any leads for a os x app, or a webapp, that can do something like this? (It seems like the kind of thing that if my programming skills weren't so rusty, could be rustled up in just a few minutes)
